QtCreator crashed and now will not start due to segfault

[TMcSquared]

I've deleted those already between installs

[mrjj]

@TMcSquared
and it still crashes ? wow. thats new.
Do you have sessions enabled ?
also , have you tried starting it from a shell (cmd)
to see if anything is written ?

also when starting in cmd.
try adding
-noload Welcome

[TMcSquared]

I get a segmentation fault when I run it from the cmdline both without and with arguments.

There's, oohh, a 1% chance that if you try running Qt Creator from within a debugger like Visual Studio (if you have that...), when it faults you'll get enough information from the stack trace to hazard a guess as to where it's going wrong...

[TMcSquared]

I just debugged it and got this: Exception thrown at 0x670E5DA7 (Qt5Core.dll) in qtcreator.exe: 0xC0000005: Access violation reading location 0x7E5B8721.

@TMcSquared

Is it possible that the wrong Qt DLLs are loaded? Have you changed the PATH environment variable, for example?

[TMcSquared]

Hmm I'll try adding it to the PATH xD

EDIT: that didn't work

[aha_1980]

@TMcSquared

No, that's not what I meant! I meant, have you done before? Or have you installed some program that did?

[mranger90]

Take a look at qt.conf in the creator/bin directory. If it's corrupted then plugins wont load.

[TMcSquared]

It's not corrupted because it's a clean install

[mranger90]

The try wiping out the creator files under AppData\Roaming\Qtproject

[TMcSquared]

already did that.

[mrjj]

@TMcSquared
Best guess is that it gets wrong QtDLLs maybe via
path.

[TMcSquared]

My PATH variable has zero Qt paths in it. even after a clean install.

[mrjj]

@TMcSquared
I have no idea then.
last test
can you start with
qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler
from shell and see if still crash ?

[TMcSquared]

:O It opened with qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler

Hi,

Then it sounds like a graphic driver issue then. Are you sure there wasn't any modification in that regard on your machine ?

[JonB]

@TMcSquared
You could check whether Windows Update snuck in and did anything since it last worked... :)

[TMcSquared]

That's completely possible, thanks for your guy's help!
@SGaist I have no idea, it quit working while I was logged in.

Hi all. Sorry to revive this topic but this problem has occurred to me as well but on an application I wrote for a client. The application was running fine. Then it crashed (just like @TMcSquared ) and hasn't opened since.
My access violation is in the QtWidgets.dll module.

Any clues? (i don't have the welcome/QmlDesigner/etc modules to disable on load as does qtcreatorI)
